your servo gets its power from your receiver which in return has its power from your ESC. which is connected to your battery .The esc gives your receiver the correct power rating of 6 volts which inturn supplies your servo of 6 volts. The 7.4 volts is for your motor.

therefore the answer ot the question is...no, you cannot run 7.4 volts into a servo that rated for 6v. i think jr just came out with a 200 dollar servo that is rated for 7.4 volts, the only way the 7.4 volts will be supplied to the servo is if the 7.4 volt pack is directly to the rx. this is typical of the lipo rx packs for running nitro. if your using an esc, chances are your only supplying 6v to your rx and servos. therefor would not be able to use the 7.4 volt servos. unless you have a voltage boost in between the esc and rx.

yes, and they have a supplementary ( blue ) tiny wire to solder to the " + " of the battery. You have to use a 4.7 picofarad bobin ( or is it micro farad ? anyway it is given with the servo) on this wire between the servo and the ESC/battery.

One tip I was given but have never tried, is to " hotwire " a slow and cheap servo (Futaba 3003, etc...) by plugging the red wire from the servo on the battery "+" instead of the receiver. It works great (more torque and speed) but its seems that it shortens the lifespan of the servo. With a 8$ servo, nobody cares, though.

Not always so, but usually. Some ESCs do not have an internal BEC circuit, and if the receiver doesn't either your servo will see the full pack voltage unless you use a receiver pack.

The Tamiya TEU-101BK ESC that comes with many of their kits is like this. I ran it for a long time with an inexpensive Futaba servo and never had a problem.

The Losi weighs slightly more than the Novak, but if you remove the switch and extra wire from the Losi, it weighs only 5-grams, less than the Novak, but you don't get a switch. The Novak units are smaller, but are a little busy with 6-wires hanging out on one end, but is probably a better choice in the end if you don't mind paying at least 50% more for the Novak unit. I have been using the Losi regulator's in my 1s LiPo 1/12 and WGT cars with a 150mah LiPo Receiver battery. The Losi using are just the right size to go on top of the Servo.
